The upper part of the blade 23, by virtue of its conformity withthe tongue extends direction as the lower part generally in the same of the standard II. The blade 23 has a point moted by the sharp double a over the rearward edges 26 on its lower end, and the point is preferably beveled as shown at 21, Fig. 5. V

As shown in Fig, 4, thewalls of the U-shaped receptacle l9 continue. into rearwardly inclined oppositely extending arms 28-1-28, the opposite end portions 29 of provide side blade supports, and to more rigidly mount side blades thereon, the supports 29 are at their ends bent downwardly into fingers 3030 as best shown in Fig. 5.

Side blades 3l3| are mounted on the fingers 30-30. These blades 3l 3 are downwardly forwardly inclined and are forwardly concave as which are bent forwardly to 1 out of the path of the tool in lumps-or cl'ods and the tool passes by, without any further action 7 shown in Fig. 2, and because of the forwardinclination of the supportsfifi and 3B, the faces 32 32 of the side blades are turned toward each-other or toward the middle blade 23 and as these side'blades iii- 31 are'p'ropelled through the soil, the faces 32-32 'therefore'have what a mold-board turning action which throws the soiltoward'the middle blade At the lower ends. of the-side blades 3 -23 i they are providedwith inwardly extending upwardly inclined 'wings 33-33:the lower edges 3434 of which are beveled preferably on both the forward and the rearward faces of the Wings.

The side blades 3l-3l are secured totheir supports 29- -29 by bolts'3535.

whileas stated, the-middle blade is and the side blades 3I-3l are downwardly forwardly inclined and forwardly concave in. their longi-.

tudinaldirections', the middle blade 23 is preferably inclined touthe ground plane at a steeper angle than the side blades 3l- '3l', and is preferably 'longer than'the side blades.

The angles which the blades 3|-3l and 23 make with'the ground will'of course vary with different depthsof theblades in the soilin use and for convenience of reference, this angle may be predetermined when the ground wheel l jand the'point 26 of the middle tool the'lower portion I! of the standard I0 is made so that it will at such position'of the tool have an angle of approximately 60 degrees with the .ground plane. a

,.In the operation of 'the'tool above described,

of the tool penetrate into the soil by whatis propelled forwardly, the blades 7 7 blade are both on'the ground plane and in such position of the 2,325,579 I f I further pro- B l-td of the zone the soil as stated is thoroughly crumbled .and ulverized and mulched, as distinguished from the action of known tools in which some of the soil which is raised by the tool is thrown on such lumps.

The inward rearward inclinationof the edges 34 causes them to perform a cutting and slicing action which reduces .the necessary propulsion force of the tool and enables them to raise the soil before turning it as described. The mold board turning action of the side blades asdelscribedturns weeds "and trash so as to prevent clogging thereof;

As a modification, the wings 33 ?3 may extend laterally: outwardly instead of inwardly, as shown in Fig; 6, at 33A-33A. F

It will be apparent, that the depend upon the exact detailsof the"construc tion illustrated and described and that changes and modifications may be made therein within the spirit of my invention' without sacrificing the aforesaid advantages and which come within the scope of the appended claims.

I claim:

' 1. In an agriculturalv soil working tool, a"

blade supports being inclined forwardly in'the Y direction of motion of the tool when in useLand; the side blades having forward longitudinally concave faces inclined transversely rearwardly, whereby to elevate longitudinally of the side blades the soil through which they are propelled to defleot and tumble it .with'a mold board turning actiomand means .to attach the tool to I an implement to support it in theyposition deports ha rapidly 'a'sthe depth increases, because of the relatively small inclination with the-horizontal rWhBllthQ tool is on the ground with zeropene tration, with the result that atjall depthsfof penetration little i forward propulsive force is necessary.

The "middle blade 7 23 raise's the :jsoil an i di- .vide's it throwing it toward the side blades 3I.3l, and these. blades; because of the moldboard action of the faces 32F -32 referred to,"lift and throw the soil toward the middle blade.

The "soil is thus. given a' double tumbling action whichpulverizes. and mulches the sameMTh'e scribed herein. 1
